中文摘要:

在系统的亢奋的支(型) 聚(合) 物的数字被调查让聚合过程给 n 我的集中的 asymptotic 表格。Thepolydispersity 代表被计算,它与古典结果的与一致。最后,因为反应是完成的份量上,数字,重量和聚合的 z 平均的度的 asymptotic 表格是评估经分解获得多分散性索引,它接近 1。

英文摘要:

The number of the hyperbranched polymers in the system is investigated for the polymerization process to give the asymptotic form of the concentration of the n-mer. The polydispersity exponent is calculated, which coincides with that of the classical result. Finally, the asymptotic forms of the number, the weight and the z-average degrees of the polymerization were evaluated analytically to obtain polydispersity index, which is close to 1 as the reaction is quantitatively completed.
